Description
Describe the bug
When doing something simple as using the form.Field, I receive the following error:
right operand of 'instanceof' is not an object
Code (check repo for more info):
const form = useForm({
defaultValues: {
firstName: "John",
lastName: "Doe",
},
onSubmit: async ({ value }) => {
// Do something with form data
console.log(value);
},
});
<form.Field
name={"firstName"}
children={(field) => (
<View>
<Text className={"bg-red-500 text-2xl"}>{field.state.value}</Text>
</View>
)}
